Application filed January 3, 1913. Serial No. H0032.

St. Louis, Missouri, have invented certainnew and` useful improvementsin Gasolene Soldering-.irons and Blow-Torches, of which the 'followingis a speeiiioation.

This invention relates to improvements in gasolene soldering irons andblow torches and has for its object a suitable fuel fluid container, enein supply mechanism@ a detaeiia'lile soldering ti and a valve forcontrolling the feed ofp the' fuel fluid under pressure to be suppliedinto the soldering tip wherein seid fuel is ignited for properly nestingsaid soldering tip.

A. `further object of my invention is to provide a suitable filteringmedium through whie i the uel'iiuid is passed and converted into e gasby thefheat Jtroni the heated soldering tip.

A further object isvto provide e gasolene soldering iron and brow torchwith o detachable soldering tip and blow torch nozzle so that the devicecan be converted from the use ot a soldering iron to that of it blowtorch. y

Figure l is e vertical sectionel Iview of m' complete invention. Fig. isa side elevation of the soldering iron tip detached. Fig. 3 is eside'elevation with a part broken away' and in section of the blow'torch nozzle or tip.

ln the construction of my invention I provide a suitable container orreceptacle Je in which the gasolene or fuel fluid is contained and isadmitted into the receptacle through the opening 5 in which is properlyinserted a screw cap or plug,I 6. ln the ond of the receptacle islocated an air pump 7, a portion thereof extending into the receptacleund a portion beyond said receptacle; in this pump is located a suitablepiston S by which air is pumped into the receptacle and as the pistonplunger is reoiprocated the air is forced into the receptacle throughthe i alre i): this air providing suitziole pressure so as to .torre thefuel duid through the nipple lo into the pipe l1: the passage ot thisduid loeiinaf oontrolled by the valve 1:2.

On the end of the pipe il .is located n cap 123 on which is soreivtlended the soldering; tip 'i-i or the blow toroh ti" or nozzlel; theinterior of the can i?. olloiv end in the sannand in the pipe lil isplaced a iiltering material 16 such as mineral wool, asbestos or othersuitable material through which the fuel fluid is to pass beforeentering into the soldering tip or torch nozzle through the opening 1Tformed in said'oap. The supply7 of duid under pressure is forced .intothe tip through the opening or jet li' in a very tine spray andinstantly ignited by the heat of the tip `supplying said tip at alltimes with sufiioient heat so that the device is in continual operation.

In iirst igniting the device, the pump is actuated to supply thereceptacle with suiiicient air, the valve l2 is operated so as to permitthe fuel under pressure to enter into the pipe 1l, passi'nff through theiller therein and spraying a ine spray into the nozzle; this spray beingignited and after the soldering tip has become properly heated the fluidis converted into a gas and such gas as is forced through the jetremains ignited for supplying said tip with sufficient heat.

The device when used as a soldering iron has merit which the ordinarysoldering iron is lacking; in this, that the iron When once properlyignited can be continuously used/ for soldering, purposes :is its heatis continuous end regular and the act of reheating the tip by placingthe same in a charcoal oven or stove as is done when using the ordinarysoldering irons is dispensed with. The instrument con housed in avertical, horizontal or any other angle or position und its Weight inthe hands of the operator is counterbalanced by reason of the fuelcarrying handle conforming in weight with that of the soldering tip; thesupply of fuel to the tip being of course regulated by the manipulationof the valve l2.

When it is desired to convert the device from a soldering iron to ablovvtorch the soldering iron tip 14 is removed and the tip 15 placed onthe cap in its stead, the gas escaping from the jet 1T forcing a 'flamethrough the end of the nozzle.
